Advantages of AAC Block
The aerated concrete dry bulk density generally is 400-800kg/m3, equivalently to clay brick 1/3, normal concrete 1/5, lower than normal light-weight aggregate concrete and hollow brick, hollow clay brick. so, using aerated concrete as wall material can lighten the building self weight, and then reduce the size of building foundation, girder and pillar etc. Structure, save building material and project cost, improve the building shock resistance.
2. Good heat preservation performance:
The aerated concrete inside have abundance tiny air hole, so it have good heat preservation performance, its coefficient of heat conductivity generally is 0.09-0.02W/(m.k), only 1/4-1/5 for clay brick, normal concrete 1/51/10. Usually 20cm thick aerated concrete wall heat preservation performance is correspond to 49cm normal clay brick wall, thus not only save heating and cooling energy, but also improve greatly building plane using coefficient.
The aerated concrete don't use coarse aggregate, has good processability, can be sawed, digged, drilling and pinning, also can be cohered by suitable binding material, which give favorable condition to building operations.
4. Wide raw material source, high production efficient, low energy consumption
The aerated concrete can be produced by sand, ore slag, fly ash, tailing ore, coal gange and quick lime, cement etc. According to local actual condition to determine variety and process, and can using industrial waste residue greatly. The aerated concrete have high production efficiency, a medium scale AAC plant, annual per capita labor efficiency can reach to 600m3, some high degree automation can reach 900-1000m3, higher than clay brick (180m3) and concrete brick (500-800m3). Its production energy consumption is low, unit product energy consumption is only 50% for same volume clay brick.Although the industrial production history of aerated concrete in China only has 40 years, its classification already developed non weight bearing block, weight bearing block, heating preservation block, wall and roof boarding, widely used in industrial and civil building, has become a new type rich vitality building material.
